Lag in displaying cursor events when a Wacom tablet is connected as NoMachine USB device
---
This Trouble Report is closed. In the current implementation, in order to get the best experience when forwarding an USB device, it's necessary that Internet connection is relatively stable and network latency between the local and the remote machine does not exceed 30ms.

How to use a graphics tablet in a NoMachine session

Our Development Team is evaluating the possibility of implementing the so called "locally terminated" forwarding also for Wacom tablets (it is already used for mouse and hard drives). Note that, if approved, this would be a completely new functionality since it's not related to the current USB forwarding already in place. Implementing such functionality it's not a short time task.

This problem has been encountered when connecting a Wacom Cintiq 13HD tablet as NoMachine USB device inside the session but it could affect also other LCD graphic tablets.

When moving the pen over the tablet, the new position of its cursor is not displayed immediately inside the NoMachine session but after a lag of about ten seconds.

Strokes and pen pressures look to work, even if there's sometimes a lag of about 0.5 second in stroke painting.

The lag in tablet pen movements is no longer noticeable for some seconds after that the mouse is moved or the mouse scroll wheel is used or when a keyboard keystroke is sent.

This problems has been reported occurring in the following environment:

NoMachine v. 6.2.4  on Windows 10 Windows x64 build 10.0.17134 (both on client and server host).
